I am attempting to write a program that will manage an external application state. The external application accepts information which is passed to it and runs a process and then exits. However, I would like to catch if an error has occurred in the application by way of identifying dialog/prompt boxes belonging to the application.
I have tried the GetWindow, EnumChildWindows API but they do not seem to identify the dialog/prompt windows. I was using the following:
public delegate bool WindowEnumDelegate (IntPtr hWnd, int lParam);
foreach (Process thisProcess in Process.GetProcesses())
{
if (thisProcess.ProcessName = "prsPDFp")
WindowEnumDelegate del = new WindowEnumDelegate(WindowEnumProc);
EnumChildWindows(thisProcess.MainWindowHandle, del, 0)
}
public static bool WindowEnumProc(IntPtr hWnd, int lParam)
StringBuilder bld = new StringBuilder(256);
GetWindowText (hWnd, bld, 256);
string text = bld.ToString();
MessageBox.Show (text, "WindowEnumProc");
return true;
The GetWindow method I have found looks loops through the child windows, but the prompt and dialog boxes do not show up - it's as if they are not childs of the main window - is this the case, if so, how can I get the information for them.
Any help/comments welcomed.
